Expanded timescale timeseries view

[krivard]

Request from @RoniRos:

It would be great if it were possible to see a time series from the beginning of the pandemic till now.

User story

• As a data power user,
• I want to see a time series with expandable or expanded x-axis limits,
• so that I can answer simple research questions about how an indicator has progressed over the full course of the pandemic, without having to write my own custom code

Additional context

One way to do this would be to bring up an overlay which full-screens the timeseries, a la the classic map.

• Is it easy to lift that code?
• How do we wanna activate this view -- click the timeseries? add an icon/link?
• Should this work on mobile (using landscape probably), or just desktop?

Some other approaches, though these all seem more complicated:

• let the user expand backwards/forwards in time directly from the main time series display
• let the user set a global viewing start date or time range in addition to setting the selected date

Hey Kate, per the expand the chart behavior, here are a few patterns that transition the time series from smaller to larger. Google Finance: change the duration with chips

Robinhood trading platform

How do you guys feel about these patterns?

I like the Google Finance chips, but I don't think we need that yet -- for now let's go with the straight-up show all dates slider and we can revisit later if we need more options.
